The test suite cannot be run until after the package is installed.
To run the test suite after installation, issue:
make check.

Now, as the root user:

make install

Command Explanations

--prefix=$(pkg-config --variable=prefix
ORBit-2.0): Setting the prefix using this parameter
instead of with $GNOME_PREFIX will ensure
that the prefix is consistent with the installation environment and
the package will be installed in the correct location.

--libexecdir=$(pkg-config
--variable=prefix ORBit-2.0)/lib/at-spi: This parameter
causes the libexec files to be installed in the preferred location
of $GNOME_PREFIX/lib/at-spi instead of
$GNOME_PREFIX/libexec.
